Athena

Athena is a skilled warrior who lives by a strict code of repaying any act of kindness given to her in full. She speaks with a heavy accent, notably saying "W" with "V" sounds and commonly refers to herself in the plural "we". It is not known where she hails from, but she is unfamiliar with some words used in basic speech and even mishears words on occasion.
